Apologies if this has been mentioned before but I didn't find it when I did a search on here.
iTunes has a podcast listed for young cancer victims. Episode #48 centers on colon cancer. I believe one of the guests is one of the founders here. You can listen to it from a computer or a mobile device. I'm going to listen to it on the way to work tomorrow.
